Acids of this element are used with a palladium catalyst to carry out the Suzuki reaction. Its hydrides add in THF solution to alkenes and are oxidized by peroxides in a reaction named for Brown. The structures of those hydrides of this element can be predicted using (*) Wade's rules. It may be found in the fibrous mineral ulexite. Its enriched 10 isotope is used to capture thermal neutrons in nuclear reators. Along with helium-3, this element is used to detect ionizing radiation in Geiger counters, and it violates the "octet rule" since it can

Its enriched 10 isotope is used to capture thermal neutrons in nuclear reators. Along with helium-3, this element is used to detect ionizing radiation in Geiger counters, and it violates the "octet rule" since it can form bonds using only its three valence electrons. For 10 points, name this metalloid with atomic number 5 and symbol B.
